=====================================================================

1. Summary:

Red Hat OpenShift Container Platform release 4.5.20 is now available with
updates to packages and images that fix several bugs.

This release includes a security update for golang for Red Hat OpenShift
Container Platform 4.5.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Description:

Red Hat OpenShift Container Platform is Red Hat’s cloud computing
Kubernetes application platform solution designed for on-premise or private
cloud deployments.

Security Fix(es):

* golang: Data race in certain net/http servers including ReverseProxy can
lead to DoS (CVE-2020-15586)
* golang: ReadUvarint and ReadVarint can read an unlimited number of bytes
from invalid inputs (CVE-2020-16845)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

This advisory contains the container images for Red Hat OpenShift Container
Platform 4.5.20. See the following advisory for the RPM packages for this
release:

https://access.redhat.com/errata/RHSA-2020:5119

Space precludes documenting all of the container images in this advisory.
See the following Release Notes documentation, which will be updated
shortly for this release, for details about these changes:

https://docs.openshift.com/container-platform/4.5/release_notes/ocp-4-5-rel
ease-notes.html

This update fixes the following bug among others:

* Previously, the Prometheus swagger definition contained a `$ref` property
which could not be resolved. This caused a runtime error to occur when
using the Prometheus operand creation form. This was fixed by adding a
`definitions` property to schema returned by the `definitionFor` helper
function so that the `$ref` property can resolve. There are no longer
runtime errors when using the Prometheus operand creation form.
(BZ#1885228)
